Isaiah 59:1 Behold, the Lord's hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: 2 But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.
[Patriarchs & Prophets pp 581] Another warning was to be given to Eli's house. God could not communicate with the high priest and his sons; their sins, like a thick cloud, had shut out the presence of His Holy Spirit. But in the midst of evil the child Samuel remained true to Heaven, and the message of condemnation to the house of Eli was Samuel's commission as a prophet of the Most High.
“The word of the Lord was precious in those days; there was no open vision. And it came to pass at that time, when Eli was laid down in his place, and his eyes began to wax dim, that he could not see; and ere the lamp of God went out in the temple of the Lord, where the ark of God was, and Samuel was laid down to sleep; that the Lord called Samuel.”
Supposing the voice to be that of Eli, the child hastened to the bedside of the priest, saying, “Here am I; for thou calledst me.” The answer was, “I called not, my son; lie down again.” Three times Samuel was called, and thrice he responded in like manner. And then Eli was convinced that the mysterious call was the voice of God. The Lord had passed by His chosen servant, the man of hoary hairs, to commune with a child. This in itself was a bitter yet deserved rebuke to Eli and his house.
1st Samuel 3:10 And the Lord came, and stood, and called as at other times, Samuel, Samuel. Then Samuel answered, Speak; for thy servant heareth. 11 And the Lord said to Samuel, Behold, I will do a thing in Israel, at which both the ears of every one that heareth it shall tingle.
May The Lord add His blessing to the study of His word. God bless!
